The browser is a custom version of Firefox 23, coupled with a Tor client and what the group calls some "custom configs".

Rather than allowing you to browse the web anonymously, instead PirateBrowser can be used to "circumvent censorship that certain countries such as Iran, North Korea, United Kingdom, the Netherlands, Belgium, Finland, Denmark, Italy and Ireland impose onto their citizens".

Any internet service provider (ISP) blockades on sites — whether government mandated or not — are automatically bypassed by the browser.

The Pirate Bay told TorrentFreak that PirateBrowser is just the first step for the group in its war on censorship. According to the site, the team is working on a BitTorrent-powered browser "which lets users store and distribute The Pirate Bay and other websites on their own".

The PirateBrowser is currently a Windows-only application, although Mac and Linux versions are on the way.
